%X In this paper the measured ecological water flow of the lower Yellow River during 1958-2000 was analyzed and the concept of ecological water requirement was discussed. Based on the unique characteristics of the Yellow River and previous research on its ecological water requirement, the present paper recommends that the water requirement for transport in the flood season and base ecological flow in non-flood season should be both included in the ecological water requirement. The water requirement for transport is 80 ×108~120 ×108 m3 per year if the bankfull discharge carries the largest sediment and contaminant load over a long period of time. The base ecological flows in non-flood season at Huayuankou and Lijin stations are 80 ×108~100 ×108 m3 and 50 ×108~60 ×108 m3, respectively. Proper regulation and control of sediment and water discharges, and quasi-market management of water resources of the Yellow River will be helpful to guarantee the above ecological water requirement.
